Abstract
A temperature compensation circuit converts a control signal (IG) that has an undesirable temperature coefficient to a temperature compensated control signal (I32) having a desirable temperature coefficient. In one embodiment, four transistors (60, 64, 68, and 72) are configured to convert the control signal (IG) having an undesirable temperature coefficient to the temperature compensated control signal (I32) having the desired temperature coefficient. Additional embodiments use components to refine the temperature compensation process.
